I think he's talking about the omc binacle, top-mount control.

Mike, I have one like yours for my 175 johnson. No obvious warm up lever or button. Grab the handle down at the pivot point and pull out. It moves out about 1/4 inch or so to disengage the shift cable. I just figured mine out not to long ago. Your supposed to be able to pull from the top of the handle, but on my old control it takes a little effort.
